I'm getting started with IDETalk, and using my GMail account to chat with a user. He has both a GMail account and an account on intellijoin.org. There are different problems with each case.
For the GMail account, talk.google.com:5222, I can login fine, see my contacts, and establish a conversation. However, each incoming message on my side is displayed TWICE. No problem with outgoing messages.
With intellijoin, I receive incoming messages but outgoing messages are rejected with a 404 error code (shown in a dialog box). My contact doesn't see any of my messages.
Where can I start troubleshooting this issue?
